1.0 Introduction

The Rice Lake Weighing Systems Ranger load cell simulators are precision instruments designed to provide
millivolt level signals for testing, calibration and troubleshooting strain gage instrumentation and systems.
Accuracy and stability are obtained through the use of a “Star Bridge” circuit comprised of four temperature stable,
precision resistors.

Rice Lake Weighing Systems offers four models of the Ranger Series S

imulators.

Ranger Simulators 1, 3 and 5 Operation 3

2.1 Sample Calculations

A Ranger simulator may be used to perform calibration of scale systems prior to installation, or test installations
prior to installation. These are NOT procedures that can be used to certify a scale, but they will provide calibration
results satisfactory for most process weigh scales. Checking the scale calibration with known weights, or product
substitution (with a verified value) is recommended.

Using a simulator, digital voltmeter, and calculator to calibrate a scale

The following tools are required:

•Ranger simulator

• Digital voltmeter (4 digit minimum, 5 digit recommended)

• Calculator

Use the following steps to calibrate a scale using a simulator, digital voltmeter and calculator.

1. Millivolt Output Average Calculation:

If load cell calibration certificates are available for the system load cells, add the full scale millivolt output
values, and divide the sum by the number of load cells in the system.

Example: 2.997 + 3.002 + 2.995 + 2.999 = 11.993 / 4 = 2.99825 mV

If the load cell calibration certificates are not available, the nominal full scale millivolt output of the load
cells is used as the average millivolt output (2mV/V or 3mV/V most common).

Unless the system load cells vary significantly from the nominal value, the calibration results will be very
similar.

2. With your digital volt meter in the volts setting, measure the excitation voltage at the junction box home

run cable +/- excitation connections, and record the value.

3. Full Scale Output Signal Calculation:

Multiply the millivolt output average value from step 1, by the excitation voltage value from step 2.

Example: 2.99825 x 9.9875 = 29.945 mV.

This is the full scale millivolt output of the scale at the total load cell capacity (individual load cell capacity
x the number of load cells in the scale).

4. Total Load Cell Capacity:

Multiply the individual load cell capacity by the number of load cells in the system.

Example: (10,000 lb x 4 = 40,000 lb) 40,000 lb is the Total load cell capacity.

5. Signal per Scale Division:

Divide the total load cell capacity from step 4 by the scale resolution value (if the scale is to be calibrated
to 25,000 x 5 lb, the scale resolution value is 5 lb). 40,000 / 5 = 8,000. This is the number of divisions over
the total load cell capacity. Divide the full scale millivolt output value from step 3 by this value.

Example: (29.945 mV / 8,000 = 0.003743 mV) this is the signal per division (signal change for each
5 lb scale change, based on the example).

6. Span Range Signal Calculation:

Multiply the signal per division value from step 5 by the number of divisions over the calibrated range of
the scale (25,000 lb / 5 - 5000 x 0.003743 - 18.715625 mV). This is the span signal range to which the
scale will be calibrated.

7. With the scale empty, perform the normal ZERO calibration procedure (refer to the indicator manual).

Enter the calibrated scale capacity as the SPAN value (25,000 in the example in Step 6).

8. With your digital volt meter set to the millivolt range, measure the signal at the junction box home run

cable +/- signal connections, and record the value. this is the scale millivolt output value at calibrated
ZERO. Example: 4.245 mV (this is a random value selected for this exercise).

9. Span Calibration Signal Calculation: Add the calibrated ZERO millivolt value from Step 8 to the Span

Range value from Step 6 (18.715625 + 4.245 = 22.960). This is the Span Calibration Signal value.

4 Ranger Simulator Operation Guide

10. Power down the digital weight indicator and disconnect the home run cable at the junction box. Connect

the home run cable to your scale simulator. Reapply power to the digital weight indicator. With your digital
volt meter set to the millivolt range, measure across the +/- signal terminals of the scale simulator, and
adjust the simulator until your volt meter value equals the Span Calibration Signal value calculated in



Step 9.

11. Perform the indicator SPAN calibration procedure (refer to the indicator manual). The load cell simulator

adjusted to the value from Step 9, is simulating the test weight load at the calibrated capacity (25,000 lb in
this example).

12. Return the indicator to the normal weigh mode. Power down the indicator, disconnect the simulator, and

reconnect the home run cable at the junction box. Reapply power to the indicator. Provided that the scale is
still empty, the indicator should read 0 lb Re-zero the scale if necessary. The scale is now calibrated.

Pre-Calibrating an Indicator Using a Simulator (Ranger 3 and 5 Only)

For this example we will pre-calibrate an indicator that will be connected to a single load cell application. The cell
capacity is 500 lbs, rated output is 2 mV/V, and the actual output on the cell’s certificate is 2.002 mV/V.

1. Calculate the units per millivolt:

Divide the load cell capacity (500) by the actual output (2.002) to get 249.7502 lbs per millivolt.

2. Calculate the actual weight expected for the 2 mV/V setting on your simulator by multiplying the value

from Step 1 (249.7502) with the mV/V setting of the simulator and get 499.5005.

3. Connect the simulator to the weight indicator and allow the indicator to warm up for 5-10 minutes.

4. Set the simulator mV/V selector switch to 0 (vernier off) and calibrate for Zero.

5. Set the simulator mV/V selector switch to the setting used in Step 2 (for this example, 2 mV/V).

6. Calibrate the span of the indicator using the actual weight expected value from Step 2 as the weight value

(WVal for most Rice Lake indicators), 499.5005 lb for this example.

7. When the indicator is connected to the actual scale, use the calibration REZERO function to account for

any deadload on the load cell.

4.0 Troubleshooting With a Simulator

The most common use for load cell simulators is diagnosing problems with electronic scale indicators or with a
strain gauge load cell scale installation. Many problems in measurement systems involve drift or other situations,
which are not repeatable. A simulator gives a fixed point from which all other system components can be judged to
be properly working. Below are some tips for using a Ranger Series simulator as a troubleshooting tool.

Is the indicator working correctly?

• Connect the simulator directly to the indicator and see if the indicator is operational.

• If the indicator’s display is drifting, or not what is expected, there may be a problem with the analog input
stage, the excitation supply, or the sense circuitry.

• Several simulators may be connected in parallel to effectively “load” down the excitation supply circuits to
check for correct operation with multiple load cells.

What is the number of display graduations with the simulator output set to different settings?

• By measuring the excitation voltage and multiplying by the setting on the simulator, the actual input signal to
the indicator can be accurately calculated.

• This may help determine whether or not there is sufficient gain and low signal sensitivity in the indicator for
operation with low output systems.

• The linearity of the indicator may also be checked this way.

• If after installation and calibration of a system, a simulator is substituted for the load cells and the value
displayed for the zero and one of the other calibrated settings (i.e., 1 mV/V) are recorded, later recalibration
or repair can be greatly simplified by direct comparison of the displayed value with the previously recorded
values.

Does the displayed value change or start drifting, after other equipment or load cells are connected?

• Problems with transient protection boards, junction boxes, auxiliary power supplies and load cell cables can
be tracked down step by step by starting at the indicator and moving the simulator(s) down the line to the
load cells.

• When testing a portion of the system, make sure all other un-tested parts of the system are not connected.

When using the vernier (Ranger 1 or 5), do setpoint outputs and the display change as expected?

• Problems with output boards, setpoint routines and batching equipment can easily be found by using the
variable vernier output of the Ranger 1 or 5 to simulate the effect of changing amounts of weight on the
system.

• In addition, inappropriate filtering settings that may not be apparent normally, may sometimes be identified
this way.

Are the load cells working properly?

• By substituting a simulator for each load cell in a system, drifting cells, unevenly loaded cells, or other cell
related problems can be identified.

• After installation of a simulator in place of a load cell, note the zero and span readings for the simulator in
that particular position (vernier turned off).

• If the zero and span readings are substantially different when the simulator is moved from cell to cell, and
these differences are not consistent with the design of the scale, suspect cells can be easily identified.
